Proteomic analysis of mycelial proteins from <Emphasis Type="Italic">Rosellinia necatrix</Emphasis>

The soilborne pathogen Rosellinia necatrix causes white root rot, a serious disease of various trees, and is extremely difficult to control. In this study, using one-dimensional electrophoresis coupled with nanoliquid chromatography-electrospray ionization quadrupole time-of-flight tandem mass spectrometry (ESI-Q-TOF-MS/MS), we identified 696 proteins from R. necatrix mycelium (KACC 40445) grown in liquid culture. In addition, 573 proteins were assigned to at least one gene ontology term including 26 functional groups. Most were related to catalytic activity in the molecular function category. This proteomic data set advances understanding of R. necatrix biology and will inform further investigations to manage white root rot using novel strategies.
